COMBINED LIGHTING AND IGNITION SYSTEM FOR AUTOMOTIVE VVEH'.llfJIifS.

Application ined November 22, 1924. semi No. 751,638,

My invention r'elatesto switches and toy ignition vand lighting systems of automobiles or other automotive vehicles employing the same. Y n

In automobile ignition and lighting systems, locks are employed to open and close theignition circuits without4 disturbing the operabilityof thelighting circuits. In one general type ot prior equipment, ignition locks have been accessible through the switch handles that were always free to control the lighting circuits, the keys themselves constituting a form oit switch handle :tor the ignition switches, the handles operating independently of the keys and the keys independently of the handles. The prior devices are thus essentially double switches, each operable independently ot the other.

Each of the circuits controlled by d the switcho my invention vhas complemental con-` tacts included inthe formation ofthe switch, a single switch operating handlebeingcom mon to the circuitsV and adapted to be in controlling relation to theirV complemental contacts, sets ofcontacts pertaining to diiierent circuits being arranged in physical succession to be adapted for control in.- succession by the handle as it is swept through its range of movement. I preferablyy keep only the parking' light circuits always Within the control of the switch handle. I include the ig-y nition and main head light Circuits within thercontrol of this handle or lock these lat-V ter two circuits from the control of the handle, as desired, but without disturbing the control of the parking lcircuits by the handle.

The handlev thus constitutes afsingle switch element Valways in control vof the parking light circuits, thishandle beingplaced in orfout of control of the'ignition and ,main head light circuits'accordingto the condition of the lock. T he main head light circuit can not thus be closed when the ignition is locked.

f then controlledby the handle. employ suppleinelfitalv head lampsto Vfurnish the front parking light, and other l sup-V plemental head lamps forv r furnishing *the dimmed head lights, but the invention isnot'` to be thus limited, it being common to estab-l;

parking circuits. l.Vllvien the lock is opened,

they handle may .have control of all circuits.

handle throughout itsy range in which all circuits may be controlled by the handle.

`Whenthe lockv is closed, the range of movement of the handle is mechanically reduced Y Y to permit the handle to retain vcontrolV of the parking light circuitsl only, the lock then preventing the handle `from moving to the contacts pertaining to the ignitionA and main head light circuits. While the switch is then limited to control ot the parking .light circuits, I do not wish to be limited to theV character of the lighting circuit or ycircuits I prefer-to lish dimming parking and dimming front head light circuits throughthe same head lamps ythat are also employed to lfurnish bright illumination.

The invention Vwill be more fully explained in connection withthe accompanying Y. draw# ings in which Fig. l is a rearor bottom view of the switching mechanism of my invention as it is preferably constructed; F ig.l 211s l a sectional view on line v2 2 of Fig. l', F 1g.Y 3 is a sectional view Aon. line S-V-Srofi Fig. 2; Fig. 4 is a sectional viewk online i-4 of Fig. 2; Fig. 5 is asectionali View on line 5 5 of Fig.- 3; Fig. v6 is a front view .I on a reduced scale; Fig1`7 isa sectional view on line 7-'7 of Fighl; and-Fig.4 Slisv a diagram showing one arrangement-.of cir-y cuits and the switching mechanism of vmy' invention asit is preferably related thereto; Y The circuit controllingv handle l. has a hub portion 2 formed` with wings or flanges 3 at its circular base or innerlendft. This circular hub base is-reely received within a circular opening 5 formed through and coaxial with the mounting and escutcheonl plate 6 that has openings 7 by which itandthe switch Y assembledv therewith may f bev ing 8 is assembled coaxially withand lbehind the plate 6 by meansof rivets l9, the outer or front end wall l0 of' theV casing-being depressed 'to a'lord a narrow space in which4 the or flanges 3 of the'ha'ndle 'may freely move when the handle is turned" upon the aX-is deiined by the circular edge of the opening A. rotatable Contact actuator .11, preferably a ring of insulating material, is assembled `with the inwardly extending;

A rotatable contact carrierA 14 shown in the forni of a I metallic ring, is interposed between .the elements 11 and-'113.- The' ring carries Contact (buttons 16,17, 18, 19, engageablezwith c`er` tain of the contacts 2O, 21, 22, 23,".2/1, 25, 26',- 27, 28, 29v pertaining to the diilerent handlel controlled lcircuits and which 'areprovided upon the. contact carrier 13 and are positioned tobe engageable at the innerflface of this carrier. The buttons 16, 17, 18, 19

The han# dle,'when turned, will turn the ring 11 and the ring will Vturn the cont-act .carrier 14 through the intermediation of the plungers 31. The'I lockincludes a barrel 32 that may be turned within a cylindrical housingT 33 that` is fixed upon and projectsoutwardly.

The ignition circuit is, however, controllable by the handle, the lock being open.

When the switch is in Park position, all the front and rear parking circuits are controllable by the handle, but the ignition and the head light circuits are locked open against control by the handle.

If the switch is lin Dim position, circuits through lamps 57, 58, 59 are closed but the other lighting circuitsare opened. The ignition circuit is controllable bythe handle, however, the lock being open.

.It the switch is thrown to Bright position, circuits through lamps 5l, 52 and 59 are closed `but the other lamp circuits are y opened. The ignition circuit is controllableV by the handle in this adjustment,y the lock being open.

In some systems, the `front parking illumination is effected by a dimming of the head lamps and without employing supplemental head lamps. Irdo not, therefore, wish to be limited to the employment of supplemental lhead lamps in the front parking light cir- Having thus described my invention, Iv

claim :fp

An electric switch including'a casing, a rotatable contact actuating ring within said casino, the inner peripheral face of said ring aving a recess formed therein providl ing a pair of spaced stop shoulders at the ends thereof, a member located within said ring and mounted on saidcasmg for movement into and out of said recess whereby the vring has limited` rotary movement when said member is disposed 'within said recess, v45

and a lock controlling the movement of said member. Y'

In Witness whereof, I hereunto subscribe my name. l
